When $5 \, g$ of $XeF_4$ gas is filled in a $6 \, L$ container at $80 \, ^oC$,the pressure exerted by the gas will be ......... $atm$.

What will be the effect on the density of $0.09 \ mol$ of a gas at $300 \ K$ if its pressure is increased?

$A$ home owner uses $4.00 \times 10^{3} \ m^{3}$ of methane $(CH_{4})$ gas (assume $CH_{4}$ is an ideal gas) in a year to heat his home. Under the pressure of $1.0 \ atm$ and $300 \ K$,the mass of gas used is $X \times 10^{5} \ g$. The value of $X$ is $.......$ (Nearest integer).
(Given $R = 0.083 \ L \ atm \ K^{-1} \ mol^{-1}$)

$A$ sample of gas has a volume of $95 \, cm^3$ at a pressure of $9.962 \times 10^4 \, N m^{-2}$ and constant temperature. What will be its volume at $10.13 \times 10^4 \, N m^{-2}$ pressure at the same temperature (in $, cm^3$)?

What is the value of $R$ in the ideal gas equation $pV = nRT$ in units of $bar \ L \ mol^{-1} \ K^{-1}$? Calculate it.

$A$ syringe has a volume of $10.0 \text{ cm}^3$ at a pressure of $1 \text{ atm}$. If the end is sealed and the plunger is pushed down at a constant temperature, what will be the final volume when the pressure becomes $3.5 \text{ atm}$ (in $\text{ cm}^3$)?
